Kobe Bryant is traveling to Germany to have another round of platelet-rich plasma therapy on his right knee, according to Adrian Wojnarowski of Yahoo! Sports.

On Thursday the Lakers confirmed Bryant had left the United States for an unnamed destination and an unnamed medical procedure unrelated to his Achilles tendon injury. The team expects him to return early next week.

Bryant underwent the procedure in 2011 while recovering from surgery to remove bone fragments from his knee. The therapy involves spinning samples of his own blood to separate the healing platelets, then injecting them back into his knee.
